I own a Sega Genesis with 32x and CD addons, PSX, PS2, GBA and PC.
I plan on picking up a Gamecube somewhere down the line but right now nothing there really appeals all that much to me 'cept Rogue Squadron.. and I'm not one to buy a console just for one game.
The Xbox I don't plan to get simply because I don't see M$ turning around and ceasing the ridiculous, offensive ad campaign they're running now.. If by some miracle they do stop pushing thier product as the only viable one and STOP trying to pull the rug out from thier competitors (Buying the OpenGL patents and probably jacking up the price to use them for Nintendo, trying to "snatch" away Squaresoft for another exclusive publisher rather than just negotiating a contract to get Square games...) then I'll go out and happily snag one along with all the cool games I've been hearing about and seeing for it.
